I have a Tivo Premium XL. Recently, I hit 98% and it started cutting off the beginnings of shows, usually by one to five minutes, but sometimes much more. I deleted a bunch of things and reduced it to 88%, hoping that would solve the problem but it didn't--it's still cutting off the beginnings of all my shows. Does anyone know what the problem is? It seems there are a lot of problems with shows cutting off at the end but not the beginning.
